The nucleus, made up of protons and neutrons, contains most of an atom's mass.
The Nucleus: it contains the heaviest particles in an atom - protons and neutrons
Almost, the entire mass of an atom is from the nucleus.
Atomic mass is based on the proton and neutron. For the most part the mass of an electron is infinitesimally small.
The "dense" central portion of an atom is called the nucleus. The nucleus of an atom contains neutrons and protons.
Protons have a positive charge and weigh 1 AMU Neutrons have a neutral charge and weigh 1 AMU Electrons have a negative charge and 1184 electrons weigh 1AMU so they are thought to add nothing to the mass of an atom. You may want to check out Bohr's model or the duet/octet rule.
There are a few layers to the atmosphere however the Troposphere is the largest part of the atmosphere containing 75% of its mass. However the Troposphere contains 99% of the water vapour on the planet as well as Earth's aerosols. It is also where all weather phenomenon will occur.
The electron is the part of the atom that accounts for electricity.
The nucleus contains the mass.
Electron. Contains basicaly no mass what so ever.
The Nucleus contains Protons and Neutrons which comprise practically all the atom's mass.
The nucleus of an atom is the densest part of an atom. It contains the protons and neutrons of an atom.
The Neucleus
The nucleus contains the majority of the mass in an atom. The nucleus contains the protons and neutrons, which each have a relative mass of 1 amu. The electrons surround the nucleus and have a relative mass of 0 amu.
In the nucleus.
Nucleus
The nucleus is the part of an atom that contains practically all its mass. In the nucleus, you can find the proton and neutron. The number of electrons, which move about the nucleus, is equal to the number of protons.
There are two main parts of an atom. The one that contains the most mass is the nucleus, which holds all of the protons and neutrons in a ball at the center of the atom. The second part is the cloud of electrons that orbit the nucleus. So, protons are found in the nucleus of an atom.
The nucleus is the most dense part of an atom.
The nucleus is the middle of the atom made up of protons (that have a positive charge) and neutrons that have no charge.
